General notes
Bear in mind that the engine can be started by
any of the vehicle occupants if there is a Smart-
Key in the vehicle (
Ypage 164).
Locking/unlocking centrally
You can start, lock or unlock the vehicle using
KEYLESS-GO. To do this, you only need carry the
SmartKey with you. You can combine the func- tions of KEYLESS-GO with those of a conven-
tional SmartKey. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using the
&
button on the SmartKey.
The driver's door and the door at which the han-
dle is used, must both be closed. The SmartKey
must be outside the vehicle. When locking or
unlocking with KEYLESS-GO, the distance
between the SmartKey and the corresponding
door handle must not be greater than 3 ft (1 m).
A brief radio connection between the vehicle
and the SmartKey determines whether a valid
SmartKey is in, or in the direct vicinity of, the
vehicle. This occurs, for example:
Rwhen starting the engine
Rwhile driving
Rwhen using HANDS-FREE ACCESS
Rwhen the external door handles are touched

HANDS-FREE ACCESS
Important safety notes
GWARNING
The vehicle's exhaust system may be very hot. You could burn yourself by touching the
exhaust system if you use HANDS-FREE
ACCESS. There is a risk of injury. Always
ensure that you only make the kicking move-
ment within the detection range of sensors.
!If the SmartKey is within the rear detection
range of KEYLESS-GO, the following situa-
tions, for example, could lead to the uninten-
tional opening of the trunk:
Rusing a car wash
Rusing a power washer
Make sure that the SmartKey is at least 10 ft
(3 m) away from the vehicle.
General notes
With KEYLESS-GO and HANDS-FREE ACCESS,
you can open or close the trunk lid or stop the
procedure without using your hands. This is use- ful if you have your hands full. To do this, make
a kicking movement under the bumper with your
foot.
Observe the following points:
RCarry your KEYLESS-GO key about your per-
son. The KEYLESS-GO key must be in the rear
detection range of the vehicle.
RWhen making the kicking movement, make
sure that you are standing firmly on the
ground and that there is sufficient clearance
to the rear of the vehicle. You could otherwise
lose your balance e.g. on ice.
RAlways ensure that you only make the kicking
movement within the detection range of sen-
sors
:.
RStand at least 12 in (30 cm) away from the
rear area while doing so.
RDo not come into contact with the bumper
while making the kicking movement. Other-
wise, the sensors may not function correctly.
RHANDS-FREE ACCESS does not function
when the engine is started.
RDirt caused by road salt around sensors :
may restrict functionality.
RUsing the HANDS-FREE ACCESS with a pros-
thetic leg may restrict functionality.
RIf a KEYLESS-GO key is within the rear detec-
tion range of KEYLESS-GO, HAND-FREE
ACCESS could be triggered. The trunk lid
could thus be opened or closed unintention-
ally, for example, if you:
-sit on the edge of the trunk.
-set something down or lift something up
behind the vehicle.
-move the charging cable through the detec-
tion range of the sensors.
-polish the rear of the vehicle.
Do not carry the KEYLESS-GO key about your
person in these situations or in situations sim-
